Krzysztof Penderecki composed an opera called Paradise Lost in two acts (divided into 42 scenes), with an English libretto by Christopher Fry, based on Milton’s epic. Penderecki called it a sacra rappresentazione, written on commission for the 1976 USA Bicentennial. The first performance was on 11/29/1978, at the Lyric Opera of Chicago. The same production was given at La Scala, Milan in 1979. Other productions were mounted in Stuttgart in April 1979 (touring to Munich and elsewhere); another in 2001 in Münster; and another in Breslau by Opera Wroclawska for the season 2009-10. For full details and illustrations see P. G. Stanwood, 'Paradise Lost, Epic and Opera', Early Modern Literary Studies 15.3 (2011). For a recorded performance of Act I Part 1 (51 minutes) see YouTube. The three further segments are also on YouTube.
